Abstract (en)
The present invention relates to a method and system (1) of engine start control for an internal combustion engine (1) having a permanently engaged starter (2), an engine block (3), a crankshaft (4) rotatably disposed within the engine block (3), a piston (5) rotatably connected to the crankshaft (4) and moveable within an associated cylinder (6), and a combustion chamber (7) in the associated cylinder (3). The starter (2) is run up to its peak revolutions per minute. Preparations are made for a first fuel injection in the combustion chamber (7) through drawing air into the combustion chamber (7). The starter (2) is shut off when the piston (5) is at minimum compression. The first fuel injection into the combustion chamber (7) is performed. Inertia of the moving parts of the internal combustion engine (1) is allowed to bring the piston (5) through a following compression and ignition of the air/fuel in the combustion chamber (7).
